Description

Seilrolle Die vorliegende Erfindung betrifft Seilrollen von kleinerer Abmessung, die aus Kunstharz hergestellt und mit einem Kugellager versehen sind. Bei diesen Seilrollen, wie sie besonders im Flugzeugbau Verwendung finden, hat man feststellen müssen, daß die Kugelläger verhältnismäßig rasch locker werden, gleichgültig, oh nun der äußere' Laufring des Kugellagers bereits vor dien Aushärtung der Seilrolle in die Preßmasse @eingebettet oder erst nachträglich mit Preßsitz eingebaut wurde. Grund für dieses bei Metall unibekannte Verhalten der Kugellager ist wahrscheinlich die dem Kunsthärz eigentumliche Eigenschaft, unter Te;mp,eraturä:nderun gen zu ermüden und dauernden Drücken gegenüber allmählich nachzugeben. Diese Ermüdungserscheinungen fallen fort, wenn auf dem äußeren Laufring des Kugellagers in an sich bekannter Weise :ein mit Kunstharz getränkter Gewebestreifen unter Druck und Hitze fest aufgeklebt ist, der mit der Seilrolle durch Kaltleim, beispielsweise durch Kau:ntleim, verbunden ist. Zui Herstellung derartiger Seilrollen sei noch bemerkt, daß mit Vorteil gleichzeitig ein ganzer Satz von Kugellagern mit eine@meinzigen kunstharzgetränkten Gewebestreifen von ausreichender Breite umwickelt und danach in .der üblichen Weise Druck und Wärme ausgesetzt wird. Die einz_elnen Kugellager lassen sich -erfahrungsgemäß auch nach dem Aushärten des Gewebestreifens leicht und glatt voneinander trennen.Pulley The present invention relates to smaller pulleys Dimensions made of synthetic resin and fitted with a ball bearing. With these pulleys, as they are used particularly in aircraft construction, one has must find that the ball bearings become loose relatively quickly, no matter oh now the outer 'race of the ball bearing before the pulley has hardened embedded in the molding compound or only subsequently installed with a press fit. The reason for this behavior of the ball bearings, which is uniquely known in metal, is likely the characteristic of synthetic resin to tire under temperature changes and gradually give in to constant pressures. These signs of fatigue fall away when on the outer race of the ball bearing in per se known Way: a strip of fabric soaked in synthetic resin is firmly glued on under pressure and heat is connected to the pulley by cold glue, for example by chewing: ntleim is. For the production of such pulleys it should be noted that with advantage at the same time a whole set of ball bearings with a @ meinzigen synthetic resin-soaked fabric strip of sufficient width and then in the usual way pressure and heat is exposed. Experience has shown that the individual ball bearings can also be reduced separate easily and smoothly from each other as the fabric strip has hardened.

In der Zeichnung ist eine Seilrolle nach der Erfindung, in Achsrichtung .gesehen, dargestellt, und zwar bezeichnet a die Seilrolle aus "Kunstharz, b das Kugellager und c einen mit Kunstharz getränkten Gewebestreifen, der erfindungsgemäß mit dem äußeren Laufring,d' des Kugellagers unter Druck und Hitze in der üblichen Weise fest verbunden und in die Seilrolle mittels Kaltleimes eingeleimt wurde.In the drawing is a pulley according to the invention, in the axial direction . Seen, shown, namely a denotes the pulley made of "synthetic resin, b the Ball bearings and c a fabric strip impregnated with synthetic resin, which according to the invention with the outer race, d 'of the ball bearing under pressure and heat in the usual Way firmly connected and glued into the pulley using cold glue.
